Figure 5.

(A) Schematic of a membrane matrix close to the percolation threshold at which the solid-ordered phase forms a continuous phase, whereas the liquid-disordered phase forms a discontinuous phase. (B) Histograms of peak heights in relation to the average surface level (0 point on x axis) in DMPC/DSPC (8:2) bilayer prepared on glass (bar graph) are shown. The peak at negative x axis values represents the fraction of the liquid-disordered phase, and the peak at positive x axis values represents the fraction of the solid-ordered phase. The grey and black curves represent Gaussian fits to the liquid disordered and solid ordered phases, respectively. To see this figure in color, go online.
